HELP
WHAT THIS IS
A diagnostics page for any file.
Detects type by “magic bytes”.
No upload • runs locally.
SCAN vs SHA-256
SCAN reads only the header (fast).
SHA-256 hashes the whole file (slower).
Large files may take time.
CONTAINER ≠ CODEC
MP4/WebM describe the container.
The codec inside may vary.
Media hints are best-effort.
SHORTCUTS
SPACE = scan (PAGE 1)
ESC = return to PAGE 1
On phone, use SETUP/RESULTS tabs.
